This document discusses hacking the Internet of Things with iOS, Ruby, Arduino and Bluetooth LE. It introduces the LightBlue Bean, a low energy Bluetooth Arduino microcontroller that can communicate with iOS, OSX, Windows and Android devices. An example use case and demo is provided of a BusyBee app that uses the LightBlue Bean and Bluetooth LE to detect when someone is on a phone call and trigger an LED notification light. Resources for further exploring iOS sensor apps with Arduino and building wireless sensor networks are also listed.
